The Development History and Performance Advantages of Volumetric Heat Exchangers

With the rapid development of the equipment industry and the improvement of living standards, volumetric heat exchangers are mainly heat exchangers that exchange heat energy or cold energy. Then, do you know what the performance characteristics of volumetric heat exchangers are? What about their historical development?

A volumetric heat exchanger can be either an independent piece of equipment, such as a heater, cooler, or condenser; or a component of a certain process equipment, such as the heat exchanger inside an ammonia synthesis tower. Due to the limitations of manufacturing technology and scientific development, early heat exchangers could only adopt simple structures, with small heat transfer areas, large volumes, and heavy weights, such as coiled tube heat exchangers.

With the development of manufacturing technology, a shell-and-tube heat exchanger was gradually developed. It not only has a large heat transfer area per unit volume but also achieves good heat transfer efficiency. For a long time, it has become a typical heat exchanger in industrial production. In the 1920s, plate heat exchangers emerged and were applied in the food industry. Heat exchangers made of plates instead of tubes, featuring a compact structure and excellent heat transfer performance, have since evolved into various forms.

In the early 1930s, Sweden developed the spiral plate heat exchanger. Subsequently, Britain used brazing to produce a plate-fin heat exchanger made of copper and its alloys, which was used for heat dissipation in aircraft engines. In the late 1930s, Sweden also manufactured plate-shell heat exchangers for pulp mills. During this period, to address the heat exchange issues involving highly corrosive media, attention began to be paid to heat exchangers made of new materials.

Around the 1960s, due to the rapid development of space technology and science, there was an urgent need for various compact heat exchangers. Coupled with advancements in stamping, brazing, and sealing technologies, the manufacturing processes of heat exchangers were further improved, thereby promoting the vigorous development and wide application of compact plate-type heat exchangers.

In addition, starting from the 1960s, typical shell-and-tube heat exchangers were further developed to meet the needs of heat exchange under high-temperature and high-pressure conditions as well as energy conservation. In the mid-1970s, to enhance heat transfer, heat pipe heat exchangers were invented based on the research and development of heat pipes.

Large temperature drop of the heat medium in volumetric heat exchangers. In steam-water heat exchange, the outlet temperature of condensed water is about 50℃, and steam traps need to be installed on the upper and lower parts of the return pipe, which facilitates use and maintenance. In water-water heat exchange, the heat temperature drop is 2-2.5 times that of the same type of heat exchanger. High-temperature hot water at 120-150℃ can be reduced to 70-75℃ after heat exchange.

Volumetric heat exchangers have good heat exchange effect, excellent heat dissipation performance, small heat loss, and are energy-saving. Meanwhile, when using steam as the heat medium, they can recover about 15% of the condensed water heat, which accounts for the total heat exchange capacity.

Small cold water area and high volume utilization rate.
